Charge behaviour and power consumption in ball mills . Aug 01, 2001 The specific power consumption for these two ball shapes is shown in Fig 16 For N≤75% there is no change in the mill power draw This occurs because the center of mass of the charge is little changed by the particle shape at these speeds At intermediate speeds, the power draw for the noncircular balls falls off rapidly

The power consumption of the ball mill was monitored for two months, and the data is shown in the histogram in Figure 2c. It can be seen that the power consumption for each shift varied between 250 and 350 kWh. The data-set is negatively skewed, and the average power consumption for each shift during this period was 294 kWh.

Consequently, a method had to be found of introducing power into the mill so as to obtain a given specific energy input. For this purpose, stirring tests with purely Newtonian liquids were carried out in absence of solids and hence, without comminution. Mathematical models are presented which describe the power consumption in agitated ball mills in absence of grinding beads. In addition, tests

the application of ball mill power from fine (minus P80 product size) to coarse material, circuit efficiency is increased and overgrinding is decreased. The other factor that determines overall circuit efficiency is how well the power that is applied to the coarse material grinds it. This is affected by design and operating variables like the media sizing and mill percent solids. From circuit
